Ivanti released security updates to address vulnerabilities in Ivanti Endpoint Manager (EPM), Ivanti Avalanche, Ivanti Connect Secure, Ivanti Policy Secure, and Ivanti Security Access Client.

CISA encourages users and administrators to review the following Ivanti security advisories and apply the necessary guidance and updates:

• Ivanti Security Advisory EPM
• Ivanti Security Advisory Avalanche
• Ivanti Security Advisory Connect Secure, Ivanti Policy Secure, and Ivanti Security Access Client

CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

• CVE-2021-26086 Atlassian Jira Server and Data Center Path Traversal Vulnerability
• CVE-2014-2120 Cisco Adaptive Security Appliance (ASA) Cross-Site Scripting (XSS) Vulnerability
• CVE-2021-41277 Metabase GeoJSON API Local File Inclusion Vulnerability
• CVE-2024-43451 Microsoft Windows NTLMv2 Hash Disclosure Spoofing Vulnerability
• CVE-2024-49039 Microsoft Windows Task Scheduler Privilege Escalation Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

1. EXECUTIVE SUMMARY

• CVSS v4 7.0
• ATTENTION: Low attack complexity
• Vendor: Rockwell Automation
• Equipment: FactoryTalk View ME
• Vulnerability: Improper Input Validation

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow a local low-privileged user to escalate their privileges by changing the macro to execute arbitrary code.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

Rockwell Automation reports that the following versions of FactoryTalk Software are affected:

• FactoryTalk View ME, when using default folder privileges: v14.0 and prior

3.2 Vulnerability Overview

3.2.1 Improper Input Validation CWE-20

A remote code execution vulnerability exists in FactoryTalk View ME. The vulnerability allows users to save projects within the public directory allowing anyone with local access to modify and/or delete files. Additionally, a malicious user could potentially leverage this vulnerability to escalate their privileges by changing the macro to execute arbitrary code.

CVE-2024-37365 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.3 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated forCVE-2024-37365. A base score of 7.0 has been calculated; the CVSS vector string is (CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.3 BACKGROUND

• CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing
• COUNTRIES/AREAS DEPLOYED: Worldwide
• COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

Rockwell Automation reported this vulnerability to CISA.

4. MITIGATIONS

Rockwell Automation has corrected this problem in V15.0.

Rockwell Automation encourages users of the affected software who are not able to upgrade to one of the corrected versions to apply the following risk mitigations where possible.

• To enhance security and help prevent unauthorized modifications to HMI project files, harden the Windows OS by removing the INTERACTIVE group from the folder’s security properties.
• Add specific users or user groups and assign their permissions to this folder using the least privileges principle. Users with read-only permission can still test run and run the FactoryTalk View ME Station.
• Guidance can be found in FactoryTalk View ME v14 Help topic: “HMI projects folder settings”. It can be opened through the FactoryTalk View ME Studio menu “helpContentsFactoryTalk View ME HelpCreate a Machine Edition application->Open applications->HMI project folder settings”.
• Security Best Practices

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more secure methods, such as virtual private networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.

4. MITIGATIONS

Bosch Rexroth has fixed this vulnerability starting with FWA-INDRV-MP-20V36. Bosch Rexroth recommends updating as soon as possible.

In use cases in which a device update is not possible or not feasible, Bosch Rexroth recommends compensatory measures which prevent or at least complicate taking advantage of the vulnerability. Always define such compensatory measures individually, in the context of the operational environment.

Some possible measures are described in “Security Manual Electric Drives and Controls”, like network segmentation. In general, it is highly recommended to implement the measures described in “Security Manual Drives and Controls”.
